Patented Got. 26, 1215.

Application filedDecember 18, 1913. Serial No. 807,514.

To all whom it may concern:

Be it known that 1, VVILLIAM A'rwoon, a citizen of the United States, residing at Longmont, in the county of Boulder and State of Colorado, have invented a new and useful Beetl-larvester, of which the following is a specification. I

The device forming the subject matter of this application is a beet harvester, and the invention aims to provide a machine of this sort in which the gaging element and the knives are arranged in a novel manner. with respect to each other, and to provide means whereby a lateral shifting of the supplemental frame which carries the knives and the gaging element may be prevented.

It is within the scope of the invention to improve generally and to enhance the utility of, devices of that type to which the present invention appertains.

lVith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of What is claimed without departing from the spirit of the invention.

In the accompanying drawings :Figure 1 shows the invention in. top plan; Fig. 2 is a side elevation, wherein sundry parts are broken away; Fig. 3 is a perspective of one of the knives; Fig. 4 is a plan showing the relative positions of the knives.

In carrying out the invention there provided an axle 1 supporting a seat 2. Ground wheels 3 are journaled onthe ends of the axle 1. A main frame 4 is secured as indicated at 5 to the axle 1 and is sustained by means of rearwardly extended braces 6 which are connected with the main frame 4 and with the axle 1. The forward end of the main frame 4 is connected as indicated at 8 with a tongue 7, the rear end of the tongue 7 being connected by means of braces 9 with the side portions of the main frame 4.

Brackets 10 are secured by means of bolts 11 or the like to the axle 1, the brackets 10 including upright guides 12. Each guide 12 is provided with a forwardly extended arm 14 and in the arms 14 is journaled for rotation a transverse shaft 15, to one end of which is secured a lever 16 rearwardly extended within easy reach of the occupant of the seat 2. The lever 16 carries a latch mechanism 17 ofv any sort, adapted to cooperate with a segment 18 secured as indicated at 19 to one of the arms 14, or upheld in any other desired manner. Fixed to the shaft 15 are segments 20, meshing into pins 21, pro ecting laterally from uprights 22 which are mounted to slide in the guides 12. If desired, the upper ends of the uprights 22 may be connected by a tie bolt 23.

Attached to the lower ends of the uprights 22 are shoes 24 which, if desired, may be provided with common slip-points (not shown). Secured to the shoes 24 and extended rearwardly from thesame are arms 7 25 which converge to form a throat 26.

The invention further includes a supplemental frame denoted generally by the nu nieral 27 and located below the main frame 4. The supplemental frame 27 preferably 1s made up of side plates 28 connected by bridges 29 and 37. If desired, colters 30 may be journaled for rotation upon the side plates 28015 the supplemental frame 27 adjacent the forward end thereof. Primary links 31 are pivoted to the main frame 4, the primary links 31 being pivotally con.- nected with inwardly extended, converging secondary links 32, the links 32 being pivotally connected with the side plates 28 of the supplemental frame 27 An upstanding link 33 is pivoted to the intermediate portion of the bridge 29, the link 33 being pivotally connected with the forward end of the lever or pedal 34, extended rearwardly to a point adjacent the seat 2, the lever or pedal 34 being fulcrumed upon a bracket 35, secured to a transverse brace 36, connecting opposed portions of the main frame 4.

Secured to the side plates 28 of the supplemental frame 27 are upright guides 38, in which are mounted to reciprocate, vertically, supports 39 which, at their upper ends, may be connected by a tie bolt 40. Journaled for rotation in the supports 39 and extended transversely of the supplemental frame 27 is a corrugated roller 41. The supports 39 maybe slotted longitudinally as indicated at 42, and clamp bolts 43 cooperating with the slots 42 are mounted in the side plates 28 of the supplemental frame 27.

The invention further includes a pair of transversely extended, triangular knives 44 and 45. The knife a5 preferably is located slightly in advance of the knife l4, and the inner ends of the knives 44: and 45 are spaced apart to define a throat-46 The forwardly presented, cutting edge of the, knife 44 however, extends to the rear of the forwardly presented, cutting edge of the knife 45, as will be understood clearly from Fig. a. The knives ll and' l5 are provided with flanges l7 whichv are bolted to the side plates 28 of the frame 27, although any other meansmay be employed for mounting the knives.

As-will be understood readily, the supplemental'frame 27 may be raised and lowered by means of the lever or pedaliA. By manipulating the lever 16, rotation may be imparted to the shaft 15, the segments of which, meshing into the pins 21. on the uprights 22will efiect a'raising and'lowering of the uprights, together with the shoes .Z-t and the arms 25. By loosening-the clamp- (ing bolts 43, the supports 39 may be raised v wardly,

and lowered, and thus the corrugated roller 41 may be adjusted vertically.

The function of the corrugated roller 41 is to regulate the depth at which the beets are toppedby the knivesttl: and Owing to the peculiar relation existing between the knives l4 and l5, as shown in Fig. it will be seen that these knives will be thoroughly efficient to top the beets, thethroat l6 servingto permit trashto pass between the inner ends of the knives. The roller 41, being corrugated, permits the leaves and the like, at the upper ends of'the beets, to pass rearwithout' interfering with the opera tion of the machine. The shoes 24 tend to loosen the ground and to detach the beets, and the rearwardly extended, converging arms '25 serve to elevate the beets, after the same have been topped.

Having thus described the invention, what is claimed is i 1. In a beet harvester, a vehicle comprising a main frame; a supplemental frame pivot'edadjacent its forward end to the main frame; a cutting means permanently secured to the supplemental frame and disposed at an acute angle to the line of advance of the harvester; guides on the supplemental frame; a supporting structure vertically adjustable in the guides; a gage roller journaled on the supporting structure; and

means engaging the supporting structure and the supplemental frame for holding the supporting structure in adjusted vertical positions in the guides.

2. In a device of the class described, a main frame; a supplemental frame suspend-- ed from the main frame, the supplemental frame embodying side members and a connection between the side members; colters carried by" the side members adjacent the forward ends thereof; a corrugated gage wheel-supported by the side members adjacent the rear ends thereof; and a cutting mechanism carried by the side members and located between the gage wheel and the colters, the colters and the gage wheel cooperatingto prevent the lateral movement of the supplemental frame with respect to the main frame, due to the action of the cutting mechanism.

3.111 a device of the class described, a main frame; a supplemental frame suspended from the main frame; means for raising and lowering the supplemental frame; a pair of converging knives carried by the supplemental frame, the cutting edge of one knife being extended to the rear of the cutting edge of the other knife, the inner ends of the knives being spaced apart to define a trash receiving throat; a colter carried by the supplemental frame and locatedin front of the knives; and a corrugated gage wheel supported by the supplemental frame and located to the rear of the knives; the colter and the gage wheel constituting groundengaging elements preventing a lateral movement of the supplemental frame due to the action of the cutting edges of the knives and preventing a lateral shifting of the trash receiving throat, during the raising and lowering of the supplemental frame.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature inv the presence of two witnesses.
